MECHANICAL MOVEMENT.

Specification of Letters Patent.

Patented Sept. 5, 1905.

Application filed September 30, 1904. Serial No. 226,706.

To all whom 2'23 may concern.-

Be it known that I, J OHANN F. Sums, a citizen of the United States, residing at Columbus,

in the county of Platte and State of Nebraska,

have invented certain new and useful Improvements in Mechanical Movements; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has relation to driving mechanism especially useful for washing-machines,

present application confine my description to its application for use upon a washing-machine and the like; and my invention consists of certain elements of combination and construction of parts, as will be hereinafter specifically referred to.

It is thought that the various objects and advantages of my invention will be clearly apparent from the following specification, though it may be briefly stated that the prime object is to provide reliably-efficient mechanism for intermittently driving the agitatingshaft of a washing-machine or the like,where by the blades upon the shaft will be caused to describe a more or less complete circle or Q revolution within the body of the machine 1 and then immediately reverse said movement 5 without interrupting the driving mechanism, thereby permitting said driving mechanism to travel continuously in the same direction.

Other objects and advantages will be hereinafter clearly presented, reference being had to the accompanying drawings, which are made a part of this application, and in which Figure 1 shows a perspective view of my invention applied to use upon a washing-machine. Fig. 2 is a detail view, in side elevation,showing the driving mechanism employed by me in agitating the shaft to which are connected the agitating-blades. Fig. 3 is a vertical central sectional view of Fig. 2. Figs. 4 and 5 are side elevations of the actuating-hub employed by me in communicating power to the agitating-shaft with the actuating parts shown in a varied position. Figs. 6 and 7 show similar views with the actuating part in a changed position. Fig. 8'shows a transverse section of the reversing-lull).

It may be briefly stated in this connection that my present invention is designed as an improvement upon my Letters Patent No.

758.939, dated May 3, 1904, inasmuch as it will i have been made in the details of construction involved in said patent, and in order to conveniently refer to the various elements of my invention and all of the parts cooperating therewith I will refer to said parts by designatingnumerals.

Rcferring to the numerals on the drawings, 1 designates the body portion of the washing-machine, churn, or the like to which my driving mechanism is to be applied, said body portion being supported by suitable legs 2,

y substantially as shown, or any desired equivchurns, and the like. although I Wlll in the alent thereof.

Upon the lid 3 of the churn I erect suitable standards I, 5. and 6, all preferably an integral part of the base member 7, whereby all of said parts may be fashioned at a single operation. The standard 4 is provided with the inwardly-directed arm 8, which has a suitable bearing-seat at its inner end to accommodate the upper end of the agitating-shaft 9, the lower end of which is provided with any suitable'form of blades or agitating devices to operate upon the clothing in the body portion 1, and I deem it unnecessary to enter specifically into details relative to the construction of said blades.

Upon the agitating-shaft 9 I reciprocatingly mount the driving-hub 10, which is provided at each end with a beveled gear, as designated by the numerals 11 and 12, and while said hub is designed to reciprocate upon said shaft it must rotate therewith, inasmuch as a longitudinally-disposcd groove 13 is formed in the upper end of said shaft, said groove being for the purpose of receiving an inwardly-directed rib let in the bore of the hub. It therefore follows that said hub is left free to slide up and down upon the shaft, but must cause the rotation of said shaft when the hub is actuated. In order to drive said hub, which is accomplished through the mediation of the gears 11 and 12, I provide the driving-shaft 15, which is supported in bearings provided in the upper ends of the standards 5 and 6, the outer end of the shaft being actuated in any preferred way, as by a powerpulley (not shown) or by a manually-operated crank 16, having the usual handle 17, as clearly shown in Fig. 1. The inner end of the shaft 15 has keyed rigidly thereto the driving-gear 18, designed to be brought intermittently into mesh with the driving-gears 11 and 12, as the case may be, and as will be hereinafter clearly set forth. Upon the inner be observed that certain important changes 1 end of the driving-shaft15 Ialso key a peculiar form of gear or controlling wheel 19, while the extreme end of the shaft 15 is properly shaped, so that ityvill cooperate with and move around in engagement with the continuous parallel walls 20 and 21, said parallel walls forming a raised rib, as clearly shown in the drawings, and the walls are connected by the curved portions 22 and 23, it being understood that the parallel sections 20 and 21 of the walls do not extend completely around the hub member 10. The office of the peculiar form of controlling-Wheel 19 is to cooperate with the compensating pins 24, 25, 26, 27, and 28 when the terminal 29 of the shaft 15 reaches one of the curved sections 22 or 23 at the end of the parallel walls 20 and 21. I also key upon the inner end of the shaft 15 the gear 30, which is peculiarly formed with inwardly projecting curved spokes or arms 31, whereby the gear 30 will be projected inward sufiiciently to come into mesh with the gear 32, which latter is permanently secured to or constitutes an integral part of the balance-wheel 33, which latter is mounted loosely upon the upper end of the shaft 9 above the bearing in the arm 8. By thus mounting the balance-wheel 33 loosely upon the shaft 9 it is obvious that said shaft may be first rotated in one direction and immediately reversed and rotated in the opposite direction, while said wheel will continuously travel in the same direction, and thus perform its oflice of imparting its impetus to the driving'mechanism through the mediation of the gears 30 and 32 and thence to the gears 11 and 12 through the mediation of the gear 18, as will be obviously apparent by reference to Fig. 2 and other views of the drawings.

From the foregoing description it will be clear that the shaft 9 has no reciprocatory movement whatever, but is intermittently driven, so that it will travel for a while in one direction and then immediately be reversed and driven in the opposite direction, thereby insuring that a more perfect agitation of the contents of the body of the washing-machine or the like will result than if said shaft was driven continuously in the same direction.

I desire to call particular attention to the auxiliary pins or members 24: to 28, inclusive, located at the ends of the parallel walls or sections 20 and 21, inasmuch as when the hub shall'have been rotated until the end 29 of the shaft 15 shall have reached the curved member 23 the gear or wheel 19 will first engage the pin 25 and be directed downward thereby around the curved portion 23 until the wheel 19 is brought into engagement with the pin 26, at which moment it will move out of engagement with said pin 25, the result being that the pin 26 will enable the wheel 19 to imparta lifting movement to the hub 10 and at the same time insure the travel of the extension or terminal 29 downward along the lower end of the curved terminal 23, bringing the wheel 19 finallyinto engagement with the pin 28, and thus starting-the extension or terminal 29 along the lower wall 21, at which time the hub 10 will have been raised sufliciently to bring the gear 12 into mesh with the gear 18. After the extension 29 has thus been started along the lower wall 21 the hub will be rotated in an opposite direction from its rotation when said extension was in engagement with the upper wall 20, as will he obviously clear. The hub will therefore be caused to rotate until the extension 29 shall have reached the curved.

member 22, when the wheel 19 will be brought successively into engagement with the pins 27, 26, and 24L, the result being that the hub will be sufficiently lowered to enter the extension 29 into engagement with the upper wall 20, at which instant the rotation of the hub is reversed, and this positive and reverse rotation of the hub is kept up continuously as long as the driving-shaft 15 is rotated, said driving-shaft 15, it being understood, being driven continuously in the same direction, while the balance-wheel 33 is also continuously rotated, insuring that its impetus and force will be applied to impart continuous rotation and steady power to the actuatingshaft 9.

The groove 13 should be continued entirely outward to the upper end of the shaft 9, whereby the hub may be readily entered in its position, so that the rib 14, formed in the bore of the hub, will be received by said groove, which is for the obvious purpose of preventing the hub from rotating on said shaft, but will permit it to rise and fall incident to the operation of the machine.

From the foregoing description, considered in connection with the accompanying drawings, it will be seen that I have provided reliably efiicient mechanism for intermittently driving the agitating-shaft of a washing-machine or the like, and since various modifications and changes may be made in the construction of my invention without materially departing from the spirit or scope thereof I desire to comprehend all possible changes and equivalents that may be regarded as falling within the purview or scope of my invention.

The various'parts may be made of any desired material and any preferred size deemed most suitable to attain the best results, and believing that the advantages and manner of using my invention have thus been made clearly apparent I will dispense with further description.

What 1 claim as new, and desire to secure by Letters Patent, is

The herein-described driving mechanism for washing-machines or the like, comprising a suitable shaft for the machine proper; a hub mounted upon the upper end of said shaft and adapted to have a reciprocating movement thereon, but arranged to rotate therewith, said hub having parallel ways 20 and 21 extending almost wholly around the hub, said parallel ways being connected at their ends by suitable curved sections 22 and 23; a gear for each end of said hub; a gear 18, a drivingshaft mounted in suitable bearings whereby power may be communicated thereto, said gear 18 being designed to be brought successively into mesh with the gears 11 and 12; said shaft having an extension adapted to cooperate with said parallel ways; a controllingwheel 19 on said driving-shaft and a plurality of pins located between the curved terminals of the parallel guideways adapted to cooperate with said gear whereby the extension on the shaft will follow from one guideway into the other and incidentally raise or lower the hub whereby the gear 18 will be broughtinto engagement with one of the gears 11 or 12,
